To all whom 'it may cdncern':

Be it known that I, LOUIS J--MovAlL-xx, acitien of the United States,residing at Oshkosh, in the county of Yinnebago and State of 'isconsin,have invented certain new and useful Improvements in Locomotives, ofwhich the following is a specification.

The invention re ates to a new and useful device or locomotive forhauling cars and i lading onv rails and has special relation to such ashaving its power furnished by internal combustion engines. T he objectof the invention is the provision and arrangement of mechanical )arts topro- 5 duce a combina-tion of simple an( substantial construction togive the maximum of tractive force to the driving wheels.

A further object is to so arrange. the parts that only simple andpositive driving mechanisin are used between the engine anddrivingwheels, and further -to have the entire mechanism and part-s above thewheels and axles rest on springs wit-hout interfering with the positivedriving mechanism.

` In the drawings Figure 1 is a side elevation of the outfit and Fig. 2a plan view.

Four drive wheels 1 are provided having a regular conventional flange 2,two wheels are keyed to axles 3 of suitable. length to suit the i0 gagef track on which the machine is to run.

A. frame of eastiron is provided comprising a built? up arrangementhaving two lside lates 4 and two ends 5, the latter -being set etweenthe side plates as shown 1n Fig. 2

and the four parts securely bolted together making a'box like rigidfram'e. The side plates have openings 6 as shown, the said.

openings are fitted with suitable half boxes 7 to forni journals orbearings which rest on the axles 3, the said boxes are capable ofsliding up vand down in the openings 'S'bu't rest on the axles at alltimes.' A spring is arranged above the boxes and rests against the sideplate at the upper end of the openings 6 so that the weight of the boxframe is at all Limes resting on the axles through the sp1 ings i andjournal boxes T, therefore the rolling of the wheels will cause thetraveling horizontally of the frame and pas-ts. connected thereto. Theend pieces ofthe frame 5 have suitable draw hars Ej attached hereto forthe urpose of coupling cars or other devices to lie hauled. Brake shoes1U are also provided for retarding or stopping the wheels quickly,

.fr the said bmke shoes have toggle joint con--v y nections 11 as shownwith arod 12 connectedl to a crank arm 13 on top of the frame, a leverl14 is connected to the cranks 13 to effect the l operationof the brakes.A G0 A reversible. internal combustion engine 15 having a suitablenumber of cylinders and preferably of the t-wo cycle type is arrangedetween the side frames and secured thereto rigidly, a H v wheel forstarting is shown at -16 65 and a sparking timer for speedl changing at,17. A friction". clutch 1S is secured to the. engine shaft with anattached .operating lever 19 also an extension 20 to a lever at theoperating end 21 so all operating devices are 70 arranged convenientlynear.A the` operator.

An extending shaft 22 from' the friction clutch is journa-led in abearing 23 wliiehis secured to the. frame, the shaft 22 has abevelpinion 24 secured thereto at the end outside 75 the bearing. Across shaft- 25 .is journaled in the frame as shown and carries a bevel`gear 26 which is meshed wit-h the pinion 24, 1t will be seen that. b vthe` revolving of the shaft 22 the shaftl'25 is driven also. sf,

A spur gear 27 is secured to the shaft 25 z4 and adapted to rotatetherewith.v Another shaft 2S is journaled in the frame below 'the shaft25 and approximatelv in line horizons tally'with the axles 3 and alsoparallel thereg5 with. A spur gear 29 is secured to the shaft 2S andadapted to mesh with the other spur gear 27. The shaft S is made thesame length as the axles 3 and has two crank arms 30,'one secured toeach end, butA arranged Aat 90 right angles or on a quarter toeachother;` vi crank pins 31 are secured therein as shown.'l Crank .pins32 are secured to the drivin wheels 1 with 'a crank radius or strokeequa to that of the crank arms 30 so that all the 95 crank pins have thesaine stroke. A link 33 is provided of suitable length with bearings ateach end to fit the crank pins 31 and 32 on each side, also another link3-1 fitted from the crank pin of one wheel to the other on each 10oside. The crank pins on the driving wheels are arranged on a quarter orat right angles to each other and with the same side `"'leading as onthe crank arnisj. It will be seen that when the crank arms 30 are rc-105 volved the. four drive wheels must `turn in unison therewith andwhile one side of cranks are on a dead center the other side is on aquarter therefrom or on the easiest pulling position and vice versa.

I n o eration, the explosive motor is started 1n either direction usinggasolcne, alcohol or kerosene as fuel and speeded up by the vtimer 17 orby a suitable throttling carburetor,

then the clutch 1,8 engaged bv means, of the lever 21, this causes thebevel pinion 24 and its meshing gear 26 to rotate which in turnl rotatesthe shaft 25 and sour gear 27, the

said spur gear meshing with the larger spur gear 29 causes ittorotatealso and in conseuence the shaft Z8 and crank arms 30, theriving wheels 1 being coupled to the crank arms 30 by the links orside'rods 33 and -34 are also caused to revolve exactly in unison and,While one set of cranks on one side are on a dead center, the oppositeset are on a quarter allowing of a goed. end efiicient rotary.transmission at any point of the revolution. It will be seen thatthereis a gradual reduction in the speeds from the engine down to thedriving shaft or drive wheels, the ratio of speeds being arranged tosuit the s eed and hauling capacity desired.l B reueing the speedsagreatleverage is ha and consequently greater hauling capacit for a givenengine ower. The frame an parts lare preferably uilt very hea ivefriction to the Wheels.. t will also be seen thatthe whole frame andparts attached thereto are resting on springs which tend-to lessen thevibratlon and with the driving shaft in approximately a horizo tal linewith the driving axles no detriment ei'ect is pro duced by an ,upwardand downward motion.

1. In a gas driven locomotive the combinationwith a suitable gas engineor motor, of a. supporting frame, having axles and shaft bearingstherein, la disenvaging clutch attached to the said engine s aft, abevel gear attached. axially with the said clutch, another bevel geararranged to mesh with the first lsaid gear and mounted on a countershaft, said shaft being journaled in the said frame and also having aspur 'gear secured thereon, a crank shaft arranged belowthe said countershaft and having a spur gear .secured thereon and adapted to mesh withthe above said spur gear, crank disks o r arms'secured to the crankshaft at each end 'thereof and having crank pins secured therein atright angles to each other, driving wheels and axlesV j ournaled in thesaid frame, crank secured to the driving wheels and at4 right angles toeach other, side rods or links adapted to connect I.the crank shaft withthe said driving wheels whereby the wheels and crank shaft revolve inunison. n

'2. In a'g'as driven :locomotive the combination .with a suitable framehaving driving Wheels and axles journaled therein, an cxplosive motormounted in said frame and aving the driving shaft extending at rightangles to the driving axles, al friction clutch attached to the drishaft of the said engine and ha b a sha extension-jo'urnaled m 'theframe, a evel pinion mounted on the s-aidshaft extension, a countershaft journaled in the frame and havinga beve gear mounted thereonarallel to the said axles and adapted to mesh with the aforesaid bevel vpinion, .a crank shaft journaled in the frame parallel vWith the saidcounter shaft and axles, andhaving cranks attached to each end thereofand adapted to extend outside the frame, s nr gears adapted to connectthe counter shaft and crankshaft, means for connecting the drivingwheels rotatably with the `crank shaft through a system of connectingvrods whereby the riving Wheels, crank shaft and lcounter'shaft revolvein unison. A In testimony whereof I hereunto affix my signature. inpresence of two witnesses.
